Option B(Triangle)
- Polygon consists of straight segments .
Sum of angles of polygon=(n-2)(180)
Polygon examples are Triangle,Square,Rectangle,pentagon etc.
Answer:
Step-by-step explanation:
F=9/5C+32 should be F = (9/5)C + 32
We are given 111 degrees F and want the same temperature in degrees Celcius.
In F = (9/5)C + 32 multiply all three terms by 5:
5F = 9C + 160, which can be solved for C:
5F - 160 = 9C
Let F = 111. Then 555 - 160 = 9C, or
395 = 9C
Dividing both sides by 9, we get C = 395/9 = 43 8/9 degrees C
14/10 is 1.4 , 1.4/ 0.2 is 7 so 0.2 is the answer
